Struct StateHashTable 

pub struct StateHashTable<K: Key, V: Value> { /* private fields */ }

StateHashTable is the main collection.

Implementations

impl<K: Key, V: Value> StateHashTable<K, V>

pub fn new() -> Self

Create a new StateHashTable. This should be an infrequent operation.

pub fn arbitary_key(&self) -> Option<K>

Return a seemingly-arbitrary key from the hash table or None if there’s no keys in the hash table. This is meant to be used for draining a server of waiters.

pub fn create_state<'a: 'b, 'b>(&'a self, key: K) -> Option<Handle<'a, K, V>>

where V: From<K>,

Create a new piece of state, returning None iff there already exists state for key.

pub fn get_state<'a: 'b, 'b>(&'a self, key: K) -> Option<Handle<'b, K, V>>

Return an existing new piece of state, returning None iff there does not exist state for key.

pub fn get_or_create_state<'a: 'b, 'b>(&'a self, key: K) -> Handle<'b, K, V>

where V: From<K>,

Return an existing piece of state, or create a new one, and always return a handle to the state for key.

Trait Implementations

impl<K: Key, V: Value> Default for StateHashTable<K, V>

fn default() -> Self

Returns the “default value” for a type.
